Fig. 4.

Developmental trajectories of stop-signal performance across ages 9–14. Panels A-D present the best-fitting models for SSRT, muS, sigmaS and tauS respectively. Fitted lines with 95 % confidence intervals were modelled by the best fitting GAMMs for each variable of interest and overlaid on the raw data points. SSRT: Stop-signal reaction time; muS: Mu of the stop-signal reaction time distribution; sigmaS: Sigma of the stop-signal reaction time distribution; tauS: Tau of the stop-signal reaction time distribution. ns: non-significant. Age in years, SST metrics in milliseconds.
